S80-P6

Available as a mezzanine add-on expansion board e.g. to the SC5-FESTIVAL and successor CPU carrier cards, the main purpose of the S80-P6 is to provide a Solid State Drive mass storage solution, and in addition to supply the backplane with eight Gigabit Ethernet ports.
The S80-P6 is equipped with an M.2 PCIe x4 socket, suitable for a high speed NVMe type SSD module, with a maximum capacity of 2TB as of current, sufficient for installation of an operating system and also data storage.

A nine-port Gigabit Ethernet switch is provided on-board. Eight ports are available for CompactPCI® Serial backplane communication via the P6 connector. Another port is connected to the local GbE controller.

The Gigabit Ethernet switch provides latest features such as 802.1 Audio Video Bridging (AVB/TSN) and Quality of Service (QoS) support, and allows light in-band managment.
Ethernet is the preferred interface for a multiprocessing configuration. With a suitable Ethernet enabled CompactPCI® Serial backplane, both networking architectures are supported, either single star for reasonable backplane cost, or full mesh for optimum system flexibility. The S80-P6 connects to the mezzanine expansion connectors HSE1 and HSE2 of the CompactPCI® Serial CPU carrier board, maintaining the 4HP (20.32mm) total assembly height.
The S80-P6 is equipped with a Marvell® 88E6390 Gigabit Ethernet switch as its main component. This device provides eight PHY ports (1-8) with integrated Gigabit Ethernet transceivers, which are wired across magnetics modules to the CompactPCI® Serial backplane connector P6.
In addition, a SerDes port (9) of the switch is connected internally to the Intel® I210-IS on-board Gigabit Ethernet controller, for switch access by the CPU card (PCI Express®).
The CPU carrier card with the S80-P6 mezzanine typically would be inserted into the system slot of a CompactPCI® Serial backplane, suitable for either star architecture networking, or full mesh backplane Ethernet. Both structures allow backplane multiprocessing and other Ethernet bound communication over P6/J6 between CompactPCI® Serial boards, with higher flexibility (and backplane cost) offered by the mesh version. An alternative application would be rear I/O Ethernet across P6 (this requires a rear I/O enabled backplane slot)
